Most adjustable height pedal pin systems tend to come loose. Our 2-way traction pins can be flipped over to change the height, and then locked down so they don't come loose. One side is a standard height, the other is about 1.5mm taller for more traction. The pedals come with 50 pins, a tube of thread lock, and an installation tool. The pins can be installed to the riders preference.
These traction pins will be used on a pratform pedal we are developing now.
